To all whom it may concern; 7

Be it known that I, GEORGE WV. DONLEY,

a citizen of the United States, residing at Modest, in the county of Clermont and State of Ohio, have invented a new and useful Improvement in Single-Pedestal Sanitary School Desk and Chair Bases, of which the following is a specification.

This invent-ion relates to certain new and useful improvements in a single pedestal sanitary school desk and chair base pedestal, the object being to provide a pedestal which is formed of two sections which can be easily and quickly disconnected in order to remove the chair bottom therefrom.

Another object of my invention is to provide a base which has a pedestal formed of two sections mounted thereon, and secured in its proper position by a central bolt.

A further object of my invention is to provide a chair base and pedestal which is exceedingly simple and cheap in construc tion, and one in which the parts are so connected together that'all danger of the parts becoming disconnected when in use is prevented.

With these objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.

In the drawing forming'a part of this specification :F igure 1 is a side elevation of my improved desk and chair base. Fig. 2 is a vertical section through the same. Fig. 3 is a section taken on line 33 of Fig. 1.

In carrying out my improved invention, I employ a circular base A on which is mounted a pedestal B having a chair arm C, said pedestal being formed of two sections having overlapping apertured lugs D and E, through which a king-bolt is adapted to pass for securing said sections together. The head of the bolt is mounted in a recess formed in the base A, and extends upwardly through the arms D and E, and through a cup nut F arranged over the top of the sections, and is locked by a suitable nut F, whereby the sections will be held together and the pedestal locked on the base by the same locking means.

The respective sections of the arms C are provided with semi-circular sockets G at their upper ends in which is mounted a ball H carrying a seat support I on which the seat or chair bottom J is secured in such a manner that the same can be swung upwardly against the desk as will be later clescribed. Extending transversely through the sections of the arm C, is a bolt K for adjusting the tension of the arms in respect to the ball, whereby said ball can be locked in said sockets so as to hold the seat in a rigid position if desired. By adjusting the sockets so as to allow the ball to turn freely therein, the seat can be raised and lowered and held in a horizontal position by the support engaging the shoulders formed in the walls of the sockets as clearly shown.

Mounted on the top of the pedestal B are arms L carrying a back M, and a desk N which is supported by braces 0 extending from the desk to the pedestal B as clearly shown, whereby the desk will be held in a rigid position. The arms L are provided with substantially semi-circular lower ends L adapted to fit within the reduced portions formed on the sides of the pedestal at the top, and the braces O are also mounted in sockets so that the desk and back can be readily removed from the pedestal.

From a foregoing description, it will be seen that I have provided a base and pedestal for a desk and chair, which is so constructed that the same can be used for supporting an opera chair.

It will also be seen that the desk and chair bottom are so mounted that they can be readily removed in order to allow the same to be thoroughly cleaned.

What I claim is 1. In a device of the kind described, a circular one piece base, a pedestal adapted to support a desk, an integral arm springing from said pedestal and adapted to support a seat, said pedestal and arm being formed in two sections, and common means for uniting two sections and also connecting the pedestal to the base. 1

2. A device of the kind described comprising a circular one piece base, a pedestal loosely mounted thereupon, said pedestal being formed of two longitudinal sections, interior overlapping lugs carried by said sectio'ns respectively, a cup nut arranged upon the upper end of the pedestal, a bolt adapted to pass through said circular base, through said lugs and the said nut, and a sectional seat supporting arm, each section of the arm being carried by one of the pedestal sections.

3. A device of the kind described comthe pedestal, common means for connecting 10 prising a circular base, a pedestal mounted together the base and the two sections of upon the base divided vertically throughout the pedestal, and means for securing a seat its entire length into tWo sections, said. sec upon said arm. tions being adapted to support a desk, an GEORGE W DONLEY arm projecting from one side of the pedestal, said arm being divided longitudinally Witnesses: into two sections, each section of the arm H. STRoNHEsvER, being integral With one of the sections of HARRY S. COLE.
